The panel is mainly used for exterior wall insulation. the middle layer :anti-combustion polyurethane or polyisocyanurate.

This production line is a kind of specialized equipment for producing laminated panels with the middle layer of anti-combustion polyurethane or polyisocyanurate or phenolic foam and with flexible facings as the top and bottom layers. The panel is mainly used for exterior wall insulation. The operation principle of this line is as follows: raw materials of rigid-foam plastic are delivered into the mixing head through the metering pump on the injection machine and then injected onto the bottom facing sheet going to conveyors along with the top superficial sheet. Between the upper and lower conveyors, the liquid materials are hardened into shape, after which the laminated sheet is edge-trimmed and, by an automatic tracking cutting mechanism, cut into segments according to the preset length.
